2-Port PCIe SATA 3.0 Expansion Controller Card, PCI-E x2/x4/x8/x16 Compatible 6Gbps SATA Adapter for SSD & HDD, Supports Windows & Linux Systems

This 2-port PCIe SATA 3.0 expansion card is a practical internal storage expansion accessory for desktops lacking enough native motherboard SATA ports. It inserts into any available PCIe x2, x4, x8 or x16 slot to add two extra high-speed SATA interfaces for hard drives and SSDs.

Each port adheres to the SATA III 6Gbps transmission standard, maintaining original disk performance during mass file backup, video editing and storage array setup. The card comes with two replaceable brackets to match full-size tower cases and compact low-profile small chassis.

Gold-plated SATA connectors and shielded PCB effectively cut electromagnetic interference and signal attenuation, supporting long-term 24-hour continuous operation without unexpected disk disconnection.

It features wide cross-system compatibility covering nearly all mainstream Windows versions and Linux operating systems. Installation is straightforward with no complex configuration required, ideal for home workstations, data storage PCs and office equipment upgrades.
